The district attorney's office accepted the plea because Menendez promised not to appeal and because of Menendez's "substantial psychiatric history and serious drug problem", Campbell said. "We are assured she'll serve a substantial amount of time behind bars."
The incident happened at night at the 40 Street-Lowery Street station in Sunnyside, Queens.
Witnesses told police a woman paced the platform and talked to herself before pushing Sen as the 11-car train entered the station. Security video showed a woman running from the scene. Menendez was recognised on a street in Brooklyn by a passerby who had seen the video and called 911, police said. "The defendant is accused of committing what is every subway commuter's worst nightmare -- being suddenly and senselessly pushed into the path of an oncoming train," Brown said on Friday. "The victim was allegedly shoved from behind and had no chance to defend himself."
